Patented J an. 22, 1907.

Application filed March 3,1906. Serial No. 304.047.

To all whom, it may concern:

Be it known that I, CHARLES SoHAAF, a citizen of the United States, residing at Washington Heights, in the county of Cook and State of Illinois, have invented new and useful Improvements in Oil-Cans, of which the following is a specification.

This. invention relates to oil-cans and the object of the invention is to provide means for preventing the nozzle of an oil-can from unscrewing accidentally, the invention being designed at the same time to permit the nozzle to be unscrewed for replenishing or cleaning the can.

With the above general object in view the invention consists in the novel construction, combination, and arrangement of parts here inafter more fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a perspective view of an oil-can, showing the nozzle-locking device applied thereto. Fig. 2 is a vertical diametrical section through the same, showing the lock in engagement with the nozzle. Fig. 3 is an enlarged detail perspective view of the locking device and the support therefor. Fig. 4 is an enlarged sectional view showing the detailed construction and operation of the locking device.

Referring to the drawings, I have therein shown the device of this invention applied to an ordinary oil-can, (designated at 1,) the same being provided with the usual threaded neck 2, in which the threaded inner end of a spout 3 is screwed, said spout for the purpose of carrying out the present invention being provided with a circumferential flange 4, the outer edge or periphery of which is notched, as shown at 5, for engaging with the locking device of this invention.

The body of the lock for preventing the nozzle from unscrewing resembles a button, the same being shown at 6. Said button or look is of concavo-convex form and is provided upon the inner side thereof with a flat leaf-spring 7, one end of which is secured fixedly to the inner side of the button or body 6, the other end being left free.

At opposite sides the body 6 is provided with inwardly-extending lugs 8, projecting toward each other and provided in their inner ends with notches 9. The body 6 is supported as a whole upon the upper and outbent extremity of a supporting-arm 10, one end of which is secured fixedly to the can, as shown at 11, by soldering the same upon the top of the can or riveting or otherwise securmg the same thereto. The upper extremity of the arm 10 is provided with oppositelyprojecting pintles 12, which lie within the lugs 8, asclearly shown in Fig. 3, the op 0- site edge of the arm 10, which is prefera ly formed of a flat metal strip, being received in the notches 9. The extreme edge of the arm 10 bears against the adjacent face of the spring '7, and said spring thus holds the button or body 6 upon the supporting-arm 10 by 9, while allowing the part 6 to turn upon the pintles 9. The part 6 is also provided with a finger or projection 13, which when the upper end of said part is moved inward engages one of the notches 5 in the flange of the spout and prevents said spout from unscrewing. It will be observed that the extreme edge of the arm 10 cooperates with the spring 7 in such manner as to hold the button 6 and the finger or projection 13 thereof either in or out of engagement with the notched flange 4. This result is produced by extending the extremity of the arm 10 beyond the axis on which the part 6 turns, as shown in Figs. 2, 3, and 4, so that when the button or body 6 is swung outward, as shown in Fig. 4, the extremity of the arm 10 bears against the spring at one side of the center of the button and sustains the button in its inoperative position, and when the upper portion of the button is pressed inward the extremity of the arm 10 presses against the spring 7 at the opposite side of the center, so as to hold the projection 13 in engagement with the notched flange, the button or detent being thus held at either limit of movement, the flange 4 limiting the movement of the button in one direction and the arm 10 limiting the movement of the button or detent in the opposite direction.

To look the nozzle of the oil-can, it is only necessary to press the upper portion of the button or detent inward, and to unlock the nozzle pressure is applied to the lower portion of the button or detent.

I claim 1. An oil-can embodying a nozzle having a threaded connection therewith and provided with a notched flange, in combination with a locking device mounted on the can and embodying an arm connected with the can, a button or detent pivotally mounted on said arm and having a projection which engages the notched flangeof the nozzle, and

forcing the notched lugs 8 against the pintles means for holding said button or detent in or out of engagement With said notched flange.

2. The combination with an oil-can havin a screw-nozzle with a notched flange, of a ocking device embodying an arm projecting from the can, a dished detent pivotally mounted on the end of said arm and provided with means for engaging the notched flange of the nozzle, and a spring carried by said detent and cooperating with the extremity of the supporting-arm to hold the 'detent either in or out of engagement With said notched flange.

3. The combination with an oil-can having a screw-nozzle and a notched flange on the nozzle, of a nozzle-locking device em-
